Abstract (en)

[origin: WO2013101081A1] A data processing system may include a high integrity storage (HIS) device with a partition or cache that is protected from updates. The data processing system may perform a boot process in response to being reactivated. The boot process may include the operation of executing a boot object. During the boot process, before executing the boot object, the data processing system may retrieve a digest for the boot object from the protected cache of the HIS device. The digest may be a cryptographic hash value for the boot object. During the boot process, the retrieved digest may be extended into a platform configuration register in a trusted platform module of the data processing system. Other embodiments are described and claimed.
